Abstract:
Previous work demonstrated the removal of nucleosomes from the PHO5 promoter upon transcriptional activation in yeast. Removal could occur by nucleosome disassembly or by sliding of nucleosomes away from the promoter. We have now activated the PHO5 promoter on chromatin circles following excision from the chromosomal locus. Whereas sliding would conserve the number of nucleosomes on the circle, we found that the number was diminished, demonstrating chromatin remodeling by nucleosome disassembly.

Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
